  High-Performance Stable n-Type Indenofluorenedione Field-Effect Transistors

  摘要：

  We developed high-performance stable n-type organic field-effect transistors (OFETs) using indenofluorenediones with different numbers of fluorine substituents (MonoF-IF-dione, DiF-IF-dione, and TriF-IF-dione). Top-contact OFETs were fabricated via the vacuum deposition of indenofluorenediones as the semiconducting channel material on polystyrene-treated SiO2/Si substrates. TriF-IF-dione FETs with Au source/drain contacts exhibited good device performances, with a field-effect mobility of 0.16 cm(2)/(V s), an on/off current ratio of 10(6), and a threshold voltage of 9.2 V. We found that the electrical stability for OFETs based on indenofluorenedione improved with the number of fluorine substituents, which was attributed to higher activation energies for charge trap creation. Moreover, the TriF-IF-dione FETs yielded excellent environmental stability properties, because the LUMO energy levels were relatively low, compared with those of the MonoF-IF-dione FETs.

  An emerging strategy to enable energy efficient gas storage and separation technologies is the development of stimuli-responsive physisorbents. Herein, we report two isostructural light-modulated adsorbents (LMAs) which undergo pressure-induced transformations from closed (non-porous) to open (porous) phases via adsorption of N2, CO2 and C2H2.

  实现高能效气体储存和分离技术的新兴战略是开发刺激响应性物理吸附剂。在此，我们报告了两种同构光调制吸附剂 (LMA)，它们通过吸附 N 2、CO 2和 C 2 H 2经历压力诱导的从封闭（无孔）相到开放（多孔）相的转变。
